MEASURE: Floor insulation between/under floor joists
Adding insulation between and/or under the floor joists of a suspended (timber) ground floor, ensuring the ventilation paths below are retained (or improved). Usually floor-boards can be retained, though in some cases may need to be replaced.
Monitoring & feedback recommended: Yes
ADVANTAGES
Reduces space-heating energy, increases thermal comfort, particularly if combined with increased floor airtightness.
